In order to investigate the dynamics and to predict the development of tropical cyclones (TC)boundary layer,theoretical and engineering models depicting the TC boundary layer flow are of great academic and practical interests. The engineering models have been widely utilized in the prediction of TC intensity,storm surge simulation and TC induced damage evaluation. Two widely accepted semi-theoretical models,including the analytical model proposed by Kepert and the similarity model by Foster,are reviewed systematically in the present study. An improved height-resolving model is proposed on the basis of Kepert’s model,where the turbulent diffusivity and drag coefficient parameterizations are incorporated. The improved model is validated through comparison with the observational data gathered from typhoon reconnaissance projects. Utilizing a set of archived over ocean surface wind field information provided by the H*wind database,rigorous comparisons among the three models are performed to examine their capability for accurately estimating the intensity,inflow angle,asymmetric characteristics and spatial distribution of the TC surface wind field.
